胎兒(er)妊(ren)娠親(qin)(qin)(qin)子(zi)(zi)(zi)(zi)鑒(jian)(jian)(jian)定(ding)(ding)(ding)也稱為(wei)胎兒(er)親(qin)(qin)(qin)子(zi)(zi)(zi)(zi)鑒(jian)(jian)(jian)定(ding)(ding)(ding)。鑒(jian)(jian)(jian)定(ding)(ding)(ding)方法有羊水親(qin)(qin)(qin)子(zi)(zi)(zi)(zi)鑒(jian)(jian)(jian)定(ding)(ding)(ding)、絨毛膜親(qin)(qin)(qin)子(zi)(zi)(zi)(zi)鑒(jian)(jian)(jian)定(ding)(ding)(ding)和(he)無創(chuang)胎兒(er)親(qin)(qin)(qin)子(zi)(zi)(zi)(zi)鑒(jian)(jian)(jian)定(ding)(ding)(ding)三種。羊水親(qin)(qin)(qin)子(zi)(zi)(zi)(zi)鑒(jian)(jian)(jian)定(ding)(ding)(ding)和(he)絨毛膜親(qin)(qin)(qin)子(zi)(zi)(zi)(zi)鑒(jian)(jian)(jian)定(ding)(ding)(ding)是傳統的產前親(qin)(qin)(qin)子(zi)(zi)(zi)(zi)鑒(jian)(jian)(jian)定(ding)(ding)(ding)，需要(yao)在(zai)三級醫院(yuan)進行手術采(cai)集樣(yang)本，而無創(chuang)胎兒(er)親(qin)(qin)(qin)子(zi)(zi)(zi)(zi)鑒(jian)(jian)(jian)定(ding)(ding)(ding)則不(bu)需要(yao)。

靜脈血胎兒親(qin)子鑒定準(zhun)確(que)嗎？

孕婦必須(xu)懷(huai)孕5 周- 分娩前。無需去醫院。從孕婦手臂上(shang)可直接抽取靜脈血(xue)約10毫(hao)升(sheng)。

這是因為孕婦的(de)靜脈血中(zhong)含有胎兒(er)DNA信息和(he)孕婦的(de)DNA，可以通過DNA實驗室分離出來(lai)，然(ran)后加入疑似父親(qin)的(de)樣本，完成DNA親(qin)子鑒定，保證了親(qin)子鑒定的(de)準確性(xing)。測試結果為99.9999%。
